// Test that MallocStackLogging=1 doesn't crash. MallocStackLogging turns on
// callbacks from mmap/munmap libc function into libmalloc. Darwin-specific
// ThreadState initialization needs to avoid calling the library functions (and
// use syscalls directly) to make sure other interceptors aren't called.

// RUN: %clangxx_tsan -O1 %s -o %t
// RUN: MallocStackLogging=1 %run %t 2>&1 | FileCheck %s
